NZ student loan overseas borrowers face two big changes: interest restarts (3.9% in 2025-26) and repayments switch from income-based PAYE deductions to fixed annual obligations tied to balance. Miss a payment and IRD charges 0.85%/month on the overdue amount.
When You Become 'Overseas-Based'
184+ days outside NZ in a 365-day period triggers overseas borrower status. Interest starts being charged from day 1 of the 184th day. Income-tested repayments stop; balance-tested fixed repayments begin (NZ$1K-$6K+ per year).
Repayment Schedule Steps
IRD's balance brackets: <$1K = pay it off. $1K-$15K = $1,000/yr. $15K-$30K = $2,000/yr. $30K-$45K = $3,000/yr. $45K-$60K = $4,000/yr. $60K-$75K = $5,000/yr. $75K-$90K = $6,000/yr. Above $90K: 7% of balance.
Interest and Penalty Stack
3.9% on full balance + 0.85%/month on overdue. Effectively 14.1% annualized if you miss payments. Stay current — IRD has reciprocal arrangements with AU, UK, CA tax authorities to collect.
Should You Pay Off vs Invest?
3.9% guaranteed return (saved interest). Beats most government bonds (2-3%), competitive with diversified equity (5-7%). Younger borrowers: spread to index funds. Older or risk-averse: pay off. Especially worth it if you plan to return to NZ — interest-free again once back.
